Answer:
21.46 cm squared
Step-by-step explanation:
3.8x5.8=21.46
The area of a shape can be calculated by multiplying its dimensions. Given a rectangle with length 0.6238 cm and width 6.6 cm, you would multiply these figures to get an area of 4.1 cm².
To calculate the area of a shape in square centimeters, you need to know the dimensions of the shape. For example, if you have a rectangle, you would multiply its length by its width to get the area. If the length was 0.6238 cm and the width was 6.6 cm, the area would be 0.6238 cm x 6.6 cm = 4.11708 cm². However, we often round to two significant figures, so the area would be 4.1 cm². Remember that area is expressed in square units, so for centimeters, the area would be in square centimeters.

Answer:
(x − 4)² + (y − 3)² = 25
Step-by-step explanation:
The equation of a circle is:
(x − h)² + (y − k)² = r²
Given three points on the circle, we can write three equations:
(1 − h)² + (7 − k)² = r²
(8 − h)² + (6 − k)² = r²
(7 − h)² + (-1 − k)² = r²
Expanding:
1 − 2h + h² + 49 − 14k + k² = r²
64 − 16h + h² + 36 − 12k + k² = r²
49 − 14h + h² + 1 + 2k + k² = r²
Simplifying:
50 − 2h + h² − 14k + k² = r²
100 − 16h + h² − 12k + k² = r²
50 − 14h + h² + 2k + k² = r²
Subtracting the first equation from the second and third equations:
50 − 14h + 2k = 0
-12h + 16k = 0
Solving the system of equations, first reduce:
25 − 7h + k = 0
-3h + 4k = 0
Solve with substitution or elimination. Using substitution, solve for k in the first equation and substitute into the second.
k = 7h − 25
-3h + 4(7h − 25) = 0
-3h + 28h − 100 = 0
25h = 100
h = 4
k = 7h −25
k = 7(4) − 25
k = 3
Now plug these into any of the original three equations to find r.
(1 − h)² + (7 − k)² = r²
(1 − 4)² + (7 − 3)² = r²
9 + 16 = r²
25 = r²
The equation of the circle is:
(x − 4)² + (y − 3)² = 25

Answer:
Step-by-step explanation:
This questions bothers permutation since permutation talks about arrangement.
The number of ways n objects can be arranged is n! ways
n! = n(n-1)(n-2)!
If a family of 5 is going on a cross-country vacation, and decided to change their seating arrangement. The total seating arrangement that they can have is;
5! = 5*4*3*2*1
5! = 20*6
5! = 120 different arrangements

Answer: 2b + -6
Step-by-step explanation: To simplify, we will use the distributive property.
Before distributing, I would change the -3 to plus a negative 3.
So we have 2(b + -3).
Now, distributing the 2 through the parenthses, we have 2(b) + 2(-3).
2(b) is 2b and 2(-3) is -6.
So we have 2b + -6 as our final answer.
Answer:
2b - 6
Step-by-step explanation:
2(b-3)=
Distribute
2*b - 2*3
2b - 6
-5/6m = -60
m = ?
Step-by-step explanation:
Hey there!
Given;
-5/6m = -60
~ Multiply "6m" and "-60".
-5 = 6m*-60
-5 = -360m
~ Divide "-5" by "-360"
m = -5/-360
m = 1/72
Therefore,the value of "m"is 1/72.
Hope it helps....
